PHOTOGRAPHIC MATERIAL AND PROCESS

摘要

A novel blocked photographically useful compound element and process are based on a new blocking group that comprises a beta-ketocarbonyl group that is part of a 5- to 7-member heterocyclic ring containing a hetero-atom not adjacent to the beta-ketocarbonyl group. Such a blocked photographically useful compound provides a photographic material and process enabling more rapid release of the photographically useful group upon processing.
